A little about Wide Angle Lenses?

Wide angle lenses are ideal for capturing large subject areas whether it is landscapes, nature, outdoor scenes, or large groups. Any lens with a focal length much smaller than 50mm is considered a wide angle lens. Its design also allows for larger views in tight spaces. That makes it great for not cutting off important subject matter when increasing the distance between yourself and the subject is impossible.

Another benefit of wide angle lenses is that they are great for accentuating the foreground keeping it super sharp. At the same time, wide angle lenses make the background seem much further away. A prominent foreground set against a receding background often results in a very pleasing effect. Compared to a standard lens, wide angles have a better depth of field and clarity. 24mm and 28mm are the most common focal lengths.
